Electrical mobility: 5.190e-8 m²/(V·s)

  • A drift velocity of 5.190e-8 m/s at 1 V/m gives a mobility of 5.190e-8 m²/(V·s).
  • This is a low mobility, consistent with large or highly solvated ions.
  • Mobility depends on the carrier mass, charge, and the frequency of collisions with the medium.

Next stepUse this mobility with the Einstein-Smoluchowski relation (diffusion mode) to find the diffusion constant for this carrier.
